CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to U.S. Provisional ApplicationNo. 62/021,261, filed on Jul. 7, 2014, the disclosure of which isincorporated herein by reference in its entirety.

BACKGROUND OF THE DISCLOSURE

1. Field of the Disclosure

The present disclosure relates generally to an adjustable seat, and morespecifically to an adjustable seat that may be raised and lowered tomultiple heights using a ratcheting-type mechanism on the seat legs andan adjustable seat that can be disengaged from a locked position andlowered using a release handle. The adjustable seat may be used in smallwatercraft.

2. Description of Related Art

Adjustable seats are desirable for many applications. One suchapplication is for use with small watercraft, such as kayaks and canoes.Users of kayaks and canoes generally prefer to utilize a seat that islow (close to the water) when they are paddling. The low position of theseat lowers the center of gravity of the watercraft, thereby increasingits stability. However, an elevated seat position may be preferred whenthe watercraft is stationary for activities such as fishing. Theelevated position provides a comfortable seating position for castingand sighting. Conventional seat adjustment mechanisms in kayaks andcanoes are often difficult to adjust. This is frequently due to designswhere the seat adjustment Mechanisms are integrated into the shell orbody of the watercraft. These prior art mechanisms require the user toadjust the seat height by removing an attachment point of the seat tothe watercraft and re-attaching the seat to another point or position onthe watercraft. Such adjustment can often be performed only while theuser is out of the watercraft. It would be desirable to develop newadjustable seats that allow for height adjustment while allowing theuser to remain seated within the watercraft.

SUMMARY OF THE DISCLOSURE

In view of the foregoing, a need exists for a stand-alone adjustableseat that is not integral or otherwise necessarily connected to the bodyof the small watercraft, such as a kayak or canoe. For example, theadjustable seat can be sold separately from any specific watercraft, andcan be used with watercraft from various manufacturers. The adjustableseat can be used with any watercraft having a beam that is wide enoughto accommodate the dimensions of the seat. The adjustable seat is notdependent upon the body of the watercraft to be either raised orlowered. Other than the points of contact where the seat is placed onthe beam of the watercraft, no other point of contact between the seatand the watercraft is needed for the height of the seat to be adjusted.

A feature of the adjustable seat is its ability to raise and lower therelative height of the seat without repositioning its points of contactwith the watercraft. In an embodiment, the relative height of the seatis set based upon the scissor action of the seat legs. The legs of theseat open and close in a scissor-like fashion and are held in place atvarying heights by an adjustment assembly that releasably locks theposition of the legs relative to one another.

In some aspects of the present disclosure, an adjustable seat mayinclude a seat base having a front end and a rear end, a front legassembly having a top end engaged with the rear end of the seat base anda bottom end opposite the top end for engaging a supporting surface, anda back leg assembly having a top end engaged with the front end of theseat base and a bottom end opposite the top end for engaging thesupporting surface. The back leg assembly may be pivotally connected tothe front leg assembly between the top end and the bottom end of thefront leg assembly and the back leg assembly.

In some aspects, the connection between top end 22of back leg assembly 18 and front end 23 of seat base 26 is a pivotingconnection about a fixed or movable pivot point to allow movement ofseat 10 from an elevated position to a lowered position. In otheraspects, such as when bottom end 20 of back leg assembly 18 is fixed toa supporting surface, top end 22 may have a slidable connection withlower portion of seat base 26 between a first position corresponding toa lowered position of seat 10 and a second position corresponding to anelevated position of seat 10. One or both top ends 16, 22 may beconnected at a fixed pivot point on seat base 26 to allow for a slidingconnection of one or both bottom ends 14, 20 to the supporting surface.In aspects where one or both top ends 16, 22 have a sliding connectionwith seat base 26, one or both bottom ends 14, 20 may be fixed to thesupporting surface.

Referring to FIGS. 3-6, top end 22 of back leg assembly 18 is connectedto adjustment assembly 30. The adjustment assembly allows the user toadjust seat base 26 to multiple seat heights, including a first or“lowered, “flush”, or “nested” position. The first position of seat 10may be particularly desirable when a user is paddling watercraft 5. Thefirst position of seat 10 lowers the center of gravity of thewatercraft, thereby increasing its stability, particularly in roughwaters. Using adjustment assembly 30 described herein, the height ofseat base 26 relative to the supporting surface can be adjusted to asecond, or “raised” or “elevated” position. The second position of seat10 may be preferred when the watercraft is stationary for activities,such as fishing. In some aspects, seat base 26 may be elevated up to 12inches between a first position and a second position. Adjustmentassembly 30 may be configured with various increments of adjustment. Insome aspects, adjustment assembly 30 may be configured with 1 inchincrements of height adjustment between 0 and 12 inches. However, thetotal height variation between the first and second position of seatbase 26 and adjustment increments between the first and second positioncan be modified to any desired size.

Adjustment assembly 30 is configured to selectively lock the position offront leg assembly 12 and back leg assembly 18, thereby adjusting theheight of seat base 26 relative to the supporting surface. Due to ascissor-like configuration of front leg assembly 12 and back legassembly 18, adjustment assembly 30 can selectively lock front legassembly 12 and back leg assembly 18 at various angles relative to eachother to adjust the height of seat base 26. For example, adjustmentassembly 30 may be used to lock front leg assembly 12 and back legassembly 18 between a first, or lowered position, where front legassembly 12 and back leg assembly 18 are substantially parallel to thesupporting surface, and a second, or elevated position, where front legassembly 12 and back leg assembly 18 are angled relative to thesupporting surface. Adjustment assembly 30 may be used to lock front legassembly 12 and back leg assembly 18 in one or more positions betweenthe first (lowered) and second (elevated) positions.

In some aspects, adjustment assembly 30 has an adjustment assemblyreceiver 42 that is connected to or formed on the underside of front end30 of both sides of seat base 26. In other aspects, a single adjustmentassembly receiver 42 may be provided on one side of seat base 26.Adjustment assembly receiver 42 may be removably or non-removablyconnected to seat base 26. In some aspects, adjustment assembly receiver42 is monolithically formed with at least a portion of seat base 26.Adjustment assembly receiver 42 has an opening 45 with a plurality ofseat height adjustment members defined on a lower end of the opening 45.The plurality of adjustment members, such as a plurality of receiverteeth 44, extend in a fore-and-aft direction of seat base 26 and areconfigured for engaging a corresponding locking member to fix a heightof seat base 26 at a desired height, as described herein. Each tooth ofthe plurality of receiver teeth 44 may correspond to a specific heightsetting of seat 10, as described herein. In some aspects, the pluralityof receiver teeth 44 may be angled toward rear end 25 of seat base 26.

With continued reference to FIGS. 3-6, top end 22 of back leg assembly18 has a locking member 39 that is configured for selectively engagingreceiver teeth on adjustment assembly receiver 42. In some aspects, apair of locking members 39 may be provided on lateral sides of seat base26 to correspond to a pair of adjustment assembly receivers 42. Lockingmember 39 is movable between an engaged position, where one or more oflocking teeth 40 are in contact with one or more receiver teeth 44, anda disengaged position, where the one or more locking teeth 40 aredisconnected from one or more receiver teeth 44. In the engagedposition, locking member 39 locks the position of front leg assembly 12and back leg assembly 18 to maintain the height of seat 10 at a desiredsetting and prevent front leg assembly 12 and back leg assembly 18 frommoving relative to one another about pivot point 24. In the disengagedposition, locking member 39 unlocks front leg assembly 12 and back legassembly 18 from one other such that height of seat base 26 may beadjusted by pivoting front leg assembly 12 and back leg assembly 18relative to one another about pivot point 24. In some aspects, lockingmember 39 may have a rod 43 (shown in FIG. 4 and FIG. 6) extendingthrough an opening 45 on top end 22 of back leg assembly 18. Rod 43 mayconnect opposing locking members 39 provided on lateral sides of seatbase 26. With rotation of rod 43 about its longitudinal axis, lockingmember 39 may be moved between the engaged position and the disengagedposition.

The locking member 39 may be movable between the engaged position andthe disengaged position using a handle 32. In some aspects, handle 32may be provided on front end 23 or on a lateral side of seat base 26.Handle 32 may be connected to locking member 39 by a cable 47 (shown inFIG. 3 and FIG. 5). In aspects where a pair of locking members 39 isprovided, cable 47 may be connected to one or both locking members 39.In such aspects, cable 47 may extend through or along a bottom portionof seat base 26 such that two sides of cable 47 are attached together athandle 32. In some aspects, pulling handle 32 away from seat base 26 maydisengage locking member 39 from the engaged position to allow theheight of seat base 26 to be adjusted.

In operation, assembly teeth 40 mate and engage with receiver teeth 44in a ratchet-type mechanism. One or both of adjustment assembly receiver42 and receiver teeth 44 are positioned in such a manner that the heightof seat base 26 can be adjusted relative to the supporting surfacedepending on the point in receiver teeth 44 where assembly teeth 40 areengaged. One skilled in the art will understand that similarinterlocking mechanisms may be used instead of the assembly teeth 40 andreceiver teeth 44 without departing from the scope of the invention. Inother aspects, the handle 32 may be replaced by a knob, wheel, button,or the like to disengage locking teeth 40 of locking member 39 fromengagement with one or more receiver teeth 44 on adjustment assemblyreceiver 42. Cable 47 may be replaced by a rigid link, a threaded rod,or a similar mechanical linkage. In some aspects, adjustment assembly 30may be hydraulically, pneumatically, or electrically operated. Forexample, adjustment assembly 30 may have one or more motors powered by apower source, such as a battery, to selectively move seat base 26between the lowered position and the elevated position. In some aspects,the arrangement of the adjustment assembly 30 may be reversed, such thatadjustment assembly receiver 42 is provided on rear end 25 of seat base26, while locking member 39 is provided on top end 16 of front legassembly 12.

As described herein, height adjustment is based on the scissor action offront leg assembly 12 and back leg assembly 18. Each possible height ofseat base 26 is obtained by assembly teeth 40 engaging and operatinglike a ratchet with receiver teeth 44 in order to obtain severalheights. Adjustment assembly 30 may be spring loaded to aid the ease ofoperation. For example, a spring (not shown) may be used to aid inraising seat 10 from a lowered position to an elevated position, or inlowering seat 10 from an elevated position to a lowered position. Seatheight may be raised by pulling handle 32 to disengage locking member 39and lifting seat base 26 to a desired height. Seat base 26 may be raisedthrough a pivoting action of front leg assembly 12 and back leg assembly18 in a scissor-like manner about pivot point 24. Once a desired heightof seat base 26 is obtained, handle 32 may be released to allow lockingmember 39 to lock adjustment assembly 30 in place. In other aspects,seat 10 may be raised by lifting seat base 26 in an upward directionwhile adjustment assembly 30 automatically moves locking member 39 froma first engagement position with receiver teeth 44 to a secondengagement position with receiver teeth 44. To lower the seat 10 from anelevated position (FIG. 7A), handle 32 may be pulled, therebydisengaging locking member 39 from engagement with receiver teeth 44(FIG. 7B). Seat base 26 may then be lowered through a pivoting action offront leg assembly 12 and back leg assembly 18 in a scissor-like mannerabout pivot point 24 (FIG. 7C). In this manner, seat 10 may be loweredand raised with only a one hand operation. In some aspects, the user mayremain seated during height adjustment of seat 10. In other aspects, theuser may sit up from seat 10 in order to raise or lower seat 10.
